The students argued over the iPod and decided to fight after school, police said.

The 12-year-old, a Baldwin resident, fearing he would be hurt in the fight, brought a gun to school. When he and the other boy met after school ended, he pulled the gun, pointed it at the other student, and said he wasn't going to fight, police said.

The alleged victim contacted school officials, who called police. Big Rapids police have the weapon, and submitted a report for review by Mecosta County prosecutors.
